The Tartan 4600 is and competitive on the racecourse.
Hull Speed
The theoretical displacement-mode speed limit — determined by waterline length, not engine or sail power.
8.4 kts
A displacement hull pushes a bow wave whose speed is limited by the waterline length.
With a waterline of 39.6′, the Tartan 4600 tops out around 8.4 knots in displacement mode — after that, the bow wave outruns the hull and resistance climbs steeply.
1.34 × √39.6′ LWL = 8.4 kts
